White Widow try 2, 3, and 4

Such odd growth. She has plenty of light she just wants to grow low and slow...sorta. her main stem is long as can be but the leaves just don't seem to be growing as fast. I'm not having much luck with the famous White Widow. If anyone has any tips on what she's picky about please let me know. I use pHd water dialed in to 6.3 and it's in FF froggy soil with extra perlite mixed in. I water approx 5" around the base yet she still doesn't seem right. My lighting is good, no problems there.
